many of the Alfonsos were from the Canaries, specifically from Icod de los Vinos in Tenerife. Many also were Afonsos, and changed their name once in Cuba. My own ancestor was Nicolas Afonso-Calidonia and changed it to Alfonso when he came to Havana in 1776. Two of his brothers also came and did the same. Many settled in Santa Maria del Rosario, Guines and other smaller towns of Havana province. These were of Portuguese extraction, as many Icodenses were. Nicolas's son was Jose Maria, and his grandson Pablo Jose. Write if any of these link up with your ancestors. Mike
